no kits, everything ends up being custom (not a whole lot of N/A's get turbo'd)

Nope.

Lots of threads have discussed this. Unless you have a lot of money, time, patience, and engineering ability, just leave it alone. It's a huge PITA.

yeah and i have something called a budget!!

i can't afford a 951, but i do have a 944 that i can turbo.

besides, i can have a better quality, better performing.
aftermarket turbo setup for less than one tune up on a 951.

now anyone here that has any information on turboing a 944

or is the smart ass that made the last post the only one to
"answer" my question.

any real help would be appreciated thank you, Chris Jobe

I'll get this one.

The only "smart ass" here is the twit asking to turbo his N/A!!!

There is much more to a turbo than just the intake.

Sell your 944 and buy a 951 then tweak it.

This has been discussed in depth many times over. Do a search.

thats the thing, the cost to turbo a 944, is at least equivalent to the purchase price of a decent 951 ($8500) so say you paid $3500 for your 944. you think 5k will give you a better quality, and more performance than a 951? i dont think its possible... but hats off to those that take on the project and persivere through all the bumps in the road.

Well, it look like im on my own then, thanks for the support guys.

I have do V-8 and 3800 V-6 motor swaps into my fieros,
I'm not afraid of the work, as for money I dont think
it would cost anywhere near $8.500 for the parts needed
for a turbo conversion, maybe you were refering to labor and parts?
i have full access to a machine shop including manual and C&C
mills and lathes. with this, and i what ive estimated near $2500
for Turbo,plumbing,boost controler,blow off valve,external waste gate,
injectors, and fuel pump.

and another (again estimated) $1200 for pistons, rings, head milling and new gaskets, and main bearings.

this would still be a fairly expensive project, but not much more than
doing the same upgrade to my 3800 powered fiero. since i would
not be using costly Porsche brand products, with the exeption of head gasket set, and conversion gasket set,

now like many of your have said, it would in many ways make more sence to buy a 951 rather than build one,

But i not into the expence for maintaining a 951.

sure there would not be a big difference in turbo parts,
but most other parts for 944 turbos are more expensive than
for N/A 944s. and since the only more expensive parts would be
the parts for the turbo conversion i would not have a inflated
cost in any other areas.

Ive just upgraded to a 1985.5 944 from my 1980 924 turbo
and am having a hard time affording parts for it, and deffenetly
could not afford parts for a 951.

i just would like the 944 to perform like the 931 did.
i may not even attemt this conversion because of the added relablity issues, but do want to know what to buy if i do. things like size of turbo.
pistons, 38mm, 40mm, or 42mm wastegate, downpipe and return .ID and .OD and so on.

Im fairly new to this forum and have not read any treads about turboing
n/a's so i made this post so i could get more informatian about it.

at lease im talking about keeping this somewhat pure by maintaining a porsche engine. and not talking about doing a chevy heart transplant,

you guys are giving me a harder time than you would someone talking about butchering up a balanced and well naturered, pure sports car by wedging in a cast iron chevy motor bettween the strut towers.

as for boosting new interest in this forum and in classic Porsche
giving newbies to the Porsche hobby like me such a hard time
is not helping.

We are helping. It's called Tuff Love.

Don't forget the special head with the ceramic lined exhaust ports and the sodium filled exhause vlaves or the thicker cylinder walls or the forged rods. There is also the larger pressure plate and clutch disk and flywheel to match. The trans has to be changed out to a beefier turbo trans or you will be throwing ring gears through the glass hatch. Then there are the larger brakes you will need to slow all those ponys down. Need to change out the suspension too. Change the front chassis for the larger radiator and intercooler. And swap out the DME, AFS for the turbo with the knock sensors.

Gee! Might save a little just buying a turbo. Imagine that.

They are not giving you a hard time, you are simply being persistant in not accepting the advice of pretty much every forum member here. It is much cheaper to get a turbo in the first place.

By the time you are done obtaining the items for a Turbo, you will basicly have bought almost all the parts for a brand new engine, and it will be a bit inferior lacking the Turbo's more effecient bodywork, and better suspension as well as an engien bay that isn't quite ideal as some things moved in the Turbo version.

I've wanted more performance from my NA, after research, turbo charging it is not the way to go. If you want more straightline speed, about the only thing you can do is move to an emmissions free state, and reprogram the ECU and remove the emmissions bits. That will liven up a TON of low end torque - Euro spec 944's where I think 140FT lb's from 2,500RPM up, where as emmissions 944's won't liven up until much later. This will give you a faster take off, and the freer setup a tiny bit more power. Thats about your best option.

When Porsche came out with their Turbo, they took a picture off all the Turbo componets that where different from a NA, a good deal of the car changed, with buying cost of a car being soo much lower then what its worth in parts, you will not save any money turbocharging a NA, which is why of course, you cannot find any kits for it, or anything else. You could do a moderate boost on the stock engien, perhaps 2-3PSI, but not what you are looking for at all.

as for heads could i use the 944s 16V or 951 heads?
could i get away with just putting bigger valves and maybe stiffer
valve springs in the 8v heads?

as far as the clutch,and trans, its an auto, but maybe lower stall converter?

brakes, well i have had a 280hp v-8 Fiero GT with its stock 9inch/single
piston calipers and it seemed to stop fine with its heavy 18" konig wheels,

so since im only adding power and not pounds, i think i can manage

i think ill have to wait on the intercooler for now, unless i could use
the old one from my 931. yes my 931 was intercooled.
not sure what brand it is but its large, about four times the thickness of
the radiator and about the same ht. and wth. no stamping or tags to identify what brand it is.

why bother with the work for the 16v head, Use the 8v head and run 951 valve springs. Run a low boost like 10psi max. I would also get a used 931 or 951 intercooler. I believe the euro 944 has high compresion so your gonna have to swap to a US 9.5cr or get some 951 pistons or get some JE custom pistons and sleeves. AS for the tranny comment the DIFFs in the NA cars SUCK. IM NA and have blown 3 diffs so far. Swap out the NA tranny for a 951 tranny. Also the AUTO tranny is gonna suck with a turbo, get rid of the auto. I would also get a wideband A/F gauge and a EGT gauge to help you une your custom turbo setup

Chris,

Sorry to say everyone is correct.

You mention 'budget'.

In doing a conversion that is the first word that is left at the door. Search and you will see the light. We have discussed this PLENTY of times. Everyone seems a little short with you because this has been discussed at nauseum.........

Thanks for the very helpful informaton, i went to the web site you
recomended, and the have built 8v heads for $499.00

i can get the intercooler from my old 931 but its aftermarket, and
the thing is HUGE i think it may block off the radiator too much.
maybe thats why the 931 spit its head gasket.

what do you think?
